How do hard drives work?

When your computer stores data on its hard drive, it doesn’t just throw magnetized nails into a box, all jumbled up together. The data is stored in a very orderly pattern on each platter. Bits of data are arranged in concentric, circular paths called tracks. Each track is broken up into smaller areas called sectors.

Is Hard drive speed important?

Is Hard Drive Speed Important? Spin speed (rotations per minute, or RPM) is relatively important. The faster a disk (platter) spins, the faster your computer can find the file you want. A 7200-RPM hard drive is obviously faster than a 5400-RPM hard drive.
